[HELP] How to update device firmware through the ThingsBoard Gateway?

[JamesLebron]

Describe the issue

Dear ThingsBoard team,

I am currently using the ThingsBoard Gateway solution, which has an MQTT connector. Following the official example, I assigned a device firmware through the ThingsBoard UI. According to the logs, I only received information such as fw_title, fw_version, fw_tag, fw_size, fw_checksum_algorithm, and fw_checksum, but did not receive the firmware download URL. Moreover, the logs indicate that fw_url is marked as deleted.

I have checked all the available documentation for the ThingsBoard Gateway, but I did not find any examples or instructions about upgrading a device through the Gateway. Could you please advise on the official recommended way to upgrade my device through the Gateway?

Connector name (If you need help with some connector/converter): MQTT Connector

Versions (please complete the following information):

• OS: [Ubuntu 20.04]
• Thingsboard IoT Gateway version [3.7.5]
• Python version[e.g. 3.1.2]

Hi @JamesLebron,

Unfortunately, it is not possible, the firmware update for devices, connected through the gateway is not implemented on ThingsBoard side. We can add the firmware/software update to the gateway devices as soon as it will be released in ThingsBoard. You can open the issue (Feature request) on the following repository https://github.com/thingsboard/thingsboard/issues.
